Hydroxypropyl methylcellulose (HPMC)ikomisheni inosiyana-siyana inoshandiswa zvakanyanya mune dzakasiyana siyanamaindasitirinekuda kweiyo multifunctional properties.Chimwe chinhu chakakosha chinokanganisa kuita kweHPMC kuchena kwayo, iyo inogona kukanganisa zvakanyanya viscosity yayo uye, nekudaro, mashandisiro ayo.Ichi chinyorwa chinotarisa mukuwirirana pakati peHPMC kuchena uye viscosity, ichijekesa zvazvinoreva muzvikamu zvakasiyana.
HPMCuye Kukosha Kwazvo:
HPMC, inotorwa kubva kune yakasikwa cellulose, inogadziriswa kemikari kugadzira polymer yekugadzira ine hunhu hunoshamisa.Mushonga uyu unowana mashandisirwo mumishonga, zvizorwa, kuvaka, nezvimwe, nekuda kwekukora, kumisa, uye kugadzira firimu.Nekudaro, kuchena kweHPMC kunobuda sechinhu chakakosha chinokanganisa mashandiro aya.
Mhedzisiro yeKuchena paViscosity:
Kuchena kunoita basa rakakosha pakuona iyo viscosity yeHPMC mhinduro.Kuchena kwepamusoro mazinga anowanzo kutungamira kune zvinowirirana uye zvinofanotaura viscosity mhedzisiro.Tsvina, seyasaracellulose, inogona kuunza misiyano mune viscosity, inokanganisa kushanda kwese kweHPMC-yakavakirwa zvigadzirwa.
Kuomesa uye Gelling Properties:
Muzvishandiso zvinoda kukora uye magelling, senge zvigadzirwa zvekudya uye kugadzirwa kwemishonga,HPMCkuchena kunokanganisa zvakananga chimiro chinodiwa uye kugadzikana.Kuchena kwepamusoro HPMC inova nechokwadi chekutonga pamusoro pe viscosity, ichipa zvigadzirwa zvepamusoro zvine hutsika hunoenderana.
Suspension Characters:
Kugona kweHPMC kumisa zvimedu mumagadzirirwo emvura kunokonzerwa nekuchena kwayo.Kusachena kunogona kutadzisa kuumbwa kwekumisikidzwa kwakagadzikana, zvichikanganisa kushanda kwemishonga yemumuromo uye zvimwe zvinomiswa.
Kugadzira Mafirimu uyeCoating:
Kuchena kunopesvedzera iyo firimu-inogadzira zvimiro zveHPMC, iyo yakakosha mumashandisirwo akaita semishonga piritsi rejasi.Inogara yakachena HPMC inovimbisa mayunifomu uye akavimbika machira, anokanganisa kuburitswa kwezvinodhaka profiles uye kugadzikana pasherufu.
Indasitiri yekuvaka:
Muchikamu chekuvaka, uko HPMC inoshandiswa sesemende yekuwedzera, kuchena kunokanganisa zvakananga simba rekuchengetedza mvura, kushanda, uye zvivakwa zvekunamatira.Yakakwirira-kuchena HPMC inobatsira kune inodiwa kuenderana uye kuita kwezvinhu zvekuvaka.
Kuchena kweHPMC yakakosha paramende inobata zvakanyanya viscosity yayo uye, nekudaro, kushanda kwayo mumaindasitiri akasiyana.Yepamusoro kuchena mazinga anotungamira kune yakavimbika uye inowirirana mhedzisiro mukukora, kumisa, uye firimu-kugadzira maapplication.Vagadziri nevatsvagiri zvakafanana vanofanirwa kukoshesa kunaka uye kuchena kweHPMC kuti ive nechokwadi chekushanda kwakakwana uye kuwedzera kushanda kwezvigadzirwa muzvikamu zvakasiyana.Sezvinoratidzwa nechinyorwa ichi, kunzwisisa pesvedzero yeHPMC kuchena pane viscosity kwakakosha kuvhura kugona kwayo kuzere mukushandisa kwakawanda.
